Angular section member for making wall corners

ABSTRACT

An angular section member for making wall corners comprises a metal sheet material having a given thickness and size, which is bent so as to provide a desired section member.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to an angular section member whichhas been specifically designed for making wall corners in buildings andthe like.

[0002] As is known, in the building field is frequently required to usean angular section member allowing to provide, in a very accurate andquick manner, the corners of masonry walls or separating walls and thelike, in any desired types of building and by busing any desired typesof construction materials and methods.

[0003] Prior approaches conventionally comprise “L”-bent sectionmembers, having a plurality of holes of a diameter of 4-5 cm through theoverall surface thereof, with the exception of the bent or folded regionthereof.

[0004] The latter is delimited by two surfaces which are bent throughabout 90°.

[0005] In operation, the user, before performing leveling operations,applies the corner protective angular section member, which, inparticular, is arranged on the corner region to be finished by plaster,adhesive materials or nails, which are caused to pass through the abovementioned small holes.

[0006] Then, the leveling operations are performed, in which the nailsare removed, if the latter must be used for fixing the section members.

[0007] In such a case, after having removed the nail elements, it isnecessary to finish again the corner to be made.

[0008] The corner protective section member or profile is usually leftin the finished work, in order to provide both a perfect finishing ofthe article of manufacture, and a reinforcement protection therefor.

[0009] Conventional section members can also be made starting from adrawn sheet metal material, in order to provide a better clampingthereof.

[0010] The subject section member, on the contrary, comprises a metalsheet element which is bent, by pressure, along a plurality oflongitudinally extending lines, to provide a profile having threedihedral angles, having a common apex.

[0011] A dihedral angle, which is herein called the inner dihedralangle, since it forms the inner portion of the construction to be made,is delimited by the two inner faces of the section member.

[0012] The remaining two outer angles, are, on the contrary, delimitedby the outer surfaces of the sides defining the inner angle, and by twoouter faces of the section member, which is bent on itself along itslongitudinal middle axis, thereby defining a projecting or raised rib.

[0013] The latter is arranged in the laying plane formed by the planecrossing the inner dihedral angle into two either equal or differentportions.

[0014] The angular element according to the present invention isdifferentiated from conventional angular elements for like application,since it comprises a reinforced rib arrangement, forming the mentionedprojecting apex tip, in addition to the two sides delimiting said innerangle, which comprise portions formed by further bending said sectionmember along two lines parallel to the middle axis thereof.

[0015] The mentioned longitudinal lines are arranged transversely ofsaid axis and are spaced at such spacings that they can be, or not,equal and symmetrical.

[0016] Moreover, a feature of the subject angular section member whichdistinguishes it from conventional angular section members is that, thethickness being the same, the subject section member has a great impactstrength or resistance, which makes its finishing operations more easyand quick.

SUMMARY OF THE INVENTION

[0017] In particular, the aim of the present invention is to providesuch an angular section member allowing to make, in an accurate andquick manner, corners of building article of manufactures having a greatimpact strength.

[0018] This aim is achieved owing to the fact that the angular sectionmember of the present invention is provided with suitable perforationsonly through the reinforced rib forming the projecting tip, or throughthe overall surface thereof, thereby providing a greater embedding ofsaid building article of manufacture, and further facilitating andaccelerating the finishing operations.

[0019] Within the scope of the above mentioned aim, a main object of thepresent invention is to provide an angular section member which can beeasily used under any constructional conditions for making saidconstructional work.

[0020] Another object of the present invention is to provide such anangular section member which, owing to its specifically designedfeatures, is very reliable and safe in operation.

[0021] Yet another object of the present invention is to provide such anangular section member which is very competitive from a mere economicstandpoint.

[0022] According to one aspect of the present invention, the abovementioned aim and objects, as well as yet other objects, which willbecome more apparent herein after, are achieved by an angular sectionmember, specifically designed for construction or building application,having the features of the accompanying claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] With reference to the number references of the above mentionedfigures, the angular section member, specifically designed for buildingconstruction, according to the present invention, and generallyindicated by the reference number 1, is made starting from a metal sheetelement 2, having a given thickness which, after having being cutpreferably to a length of 300 cm, is bent or folded upon.

[0033] More specifically, said sheet metal element 2 is bent along itsmiddle longitudinal axis, so as to provide two sheet metal portionsoverlapping one another, thereby providing a reinforced and projectingrib 3 the corner 4 of which, in addition to laying on the direction ofthe middle axis, provides the corner of the desired angle of the masonryarticle of manufacture.

[0034] The two side portions or flaps 5 and 6 are so bent as to providea suitable angle along the longitudinal lines 8 and 7.

[0035] The latter, in particular, are preferably, through notnecessarily, arranged at equal spacings and are symmetrical with respectto the middle longitudinal axis.

[0036] Thus, a section member defining three dihedral angles, i.e. aninner dihedral angle 11 and two outer dihedral angles 9 and 10, allhaving their vertex at a single ideal point 12, is provided.

[0037] More specifically, said section member is so perforated as toprovide a plurality of throughgoing holes 13, having a set diameter,which can affect only the surfaces of the projecting rib 3, as shown inFIG. 1, or the overall surfaces of the sheet metal element 2, as shownin FIG. 3.

[0038] The mentioned perforations or holes allow the subject metalsection member to be fully embedded in the building or constructionalfilling-in and finishing materials.

[0039] Thus, due to the above mentioned reason, the provision of thementioned holes at different regions of the section member depends onthe building materials and methods which are used for providing thefinished masonry article of manufacture.

[0040] In the embodiment shown in FIG. 3, the subject section membermust be embedded in the masonry material so as to also affect theportions 5 and 6 delimiting the inner dihedral angle 11.

[0041] The latter receives the tile or masonry element 14, whereas theprojecting rib 3 is embedded in the plaster and finishing material,forming the surface layers 15 and 16 of the wall corner.

[0042] In the case of plaster-paperboard wall corners, as shown in FIGS.5 and 6, the portions or flaps 5 and 6 of the inner dihedral angle 11are abutted against the walls of a metal bearing column 17 of thepaperboard-plaster wall construction and are clamped to saidconstruction by iron clamping screws 18.

[0043] The panels 19 and 20 bears, in a flush relationship with the endportions of the projecting tip 3, the level of the two walls forming thecorners.

[0044] In this connection it should be pointed out that finishingplaster and other materials will embed also in this case the sectionmember therein.

[0045] As clearly shown in FIG. 7, the section members can be buttjoined by introducing a metal plate 21, having suitable size, thicknessand holes, at the recesses housing the clamping screws 22.

[0046] The mentioned metal plate 21, having preferably a rectangularconfiguration, is arranged and clamped in the bending or fold 23 insidethe projecting rib 3.

[0047] The section member according to the present invention can be madein modified embodiments providing to change the inner angle 11, to allowwalls having several types of angles to be easily made.

[0048] Further modified embodiments can be also performed with respectto the angular opening of the fold 23 inside the projecting corner 3.

[0049] Thus, it is possible to provide a facilitated storing andshipment, since the subject section members can be overlapped onto oneanother, by providing the folded portion 23 with a suitable opening.

[0050] From the above disclosure it should be apparent that theinvention fully achieves the intended aim and objects.

[0051] In particular, a very practical and functional system has beenprovided, allowing to easily make an angular section member for buildingapplication, which can be used for making, in a very accurate and quickmanner, any desired corners, having any set angle, both in walls ordividing construction and the like.

[0052] The invention, as disclosed, is susceptible to severalmodifications and variations, all of which will come within the scope ofthe invention.

[0053] Moreover, all of the constructional details can be replaced byother technically equivalent elements.
